Corrosion protection

Metals have a special place in our daily lives. Regardless of whether it’s about driving a car or playing with trinkets, metal has surrounded our world. There is no worse feeling than when your car starts to turn orange, right? The fact is that the world of metal is struggling with the scourge of corrosion.

Here are some tips you can take into account if you want to be sure that your metal treasures will not corrode:

Choosing the right metal

The simplest way to protect metal objects from corrosion is to make sure that they are made of metal types that will not rust. It’s quite simple, right? Why bother so much with rust protection when it’s enough to choose a metal that will not rust. Below are some examples:


Aluminum is a corrosion-resistant metal, ideal in places exposed to Mother Nature.

stainless steel

Stainless steel is an alloy; Corrosion resistance in this case depends on its composition. Both types used: 316 and 304 are both corrosion resistant.

Steel with increased resistance to weather conditions

It is cheaper than stainless steel but does not offer the same corrosion resistance as stainless steel.

Making mistakes is an inseparable part of life. One of them is the choice of a metal that is not corrosion resistant. If this happens, do not panic. WD-40 is here to help you. Apply WD-40 Specialist Penetrant to create a special protective layer on the entire metal surface. Thanks to this, you will be sure that metal objects will not be eaten by rust. Regardless of whether your metal treasure is made of aluminum or iron, WD-40 will protect it the same. The WD-40 Specialist Penetrant  can also be used if the rust problem already exists and you want to remove it. Saves life right?

Protection against surroundings

Parents often want to protect their children from the outside world, claiming that it can have a negative impact on their children. However, when it comes to metal objects, such precautions are not taken. Why? The interaction of metal with the environment may have worse effects than the interaction of children with the environment. It is important to protect the metal by limited exposure to moisture. It destroys metals in the same way that bandits can hurt a child. Do you understand what I mean?

However, in the case of metal, you can “buy” protection. Thanks to measures such as WD-40, you do not have to worry about rust or corrosion. Just spray the metal from time to time with WD-40 .

The project is important

Below you will find a few things to keep in mind when designing metal objects and the desire to protect them from corrosion:

  • Try to avoid patterns with holes and slits. It is in them that water is collected, which causes corrosion.
  • Make sure that the joints are welded rather than bolted. Imagine a combination of a rusty screw – it will not be good, right?
  • A continuous flow of air should be ensured. If this is not the case, the moisture will be there in the frame of the passage of time.
  • In the case of large, metal objects, appropriate spaces should be maintained between their individual parts, so as to provide space for maintenance work.

However, if you have bought a beautiful metal object that is not made in accordance with the above instructions, spray it with WD-40 as soon as possible. Thanks to this, protection against corrosion will take place immediately. Believe me, in the fight against corrosion, you can not afford delays.


The galvanization process is the coating of metals that are susceptible to corrosion, such as iron zinc. The zinc layer will act as protection against the ingress of corrosive substances into the metal.

Of course, the layer of corroded zinc will not look good on your precious metal items. It denies them buying them at all. For valuable items, it is better to use other options, and it is best to use them WD-40.

World of coatings

There are many coatings that will help you protect metal objects.

  • Cover the object with a layer of corrosion-resistant metal, protects it against corrosion. It will act as a barrier between the environment.
  • Small metal objects can be immersed in a solution of sodium chloride, potassium nitrate and water. However, it is only a product that works in a short period of time and gives objects a blue and black color. It does not look aesthetically pleasing, therefore it is rarely used.
  • Oil-based coatings can also be used. They are quite cheap and stop the penetration of oxygen and water.

Maintenance works wonders

Regular maintenance can work wonders when it comes to removing rust. Corrosion protection is a regular process. However, this requires time – quite a lot of time – and that is what each of us has little in modern times.

WD-40 tests

Brownells Gunsmithing Supply conducted tests to prove which substance is the best in corrosion protection. The results have been made public. According to them, the WD-40 is the best of its kind. The abbreviation WD can be developed as “Water Displacement”, which is exactly what this product does. Products such as the multifunctional WD-40 and WD-40 Specialist Penetrant can not only protect against corrosion but also remove it when it occurs.

Corrosion protection is not so difficult. Just spray the WD-40 surface. That’s all it takes to make everyday life easier – which is becoming more complicated day by day.
